Hi. I have made a few nodes that take some geo, pack it and by using rig doctor make joints. In the screen grab I have a few spheres pretending to be arms, So far I can auto build the joints and hierarchy. But only on one thing at a time. IE arms, legs, etc.

I am trying to work out how I can feed in multiple parts to be rigged. IE, Arms and Legs and it automatically make the correct joints and structure. It feels like I need a new for loop that will somehow group similar named bits of geo (legs_01_jnt, legs_02_jnt)and (arms_01_jnt, arms_02_jnt) so when I run the add SOP though it I get all the correct structures built. Hopfully this post makes sense. I can see the finish line but cannot reach it. Any help would much appreciated :-)

Best. Mark
